Band-Pass Filters – Do You Actually Need One?

Post author By admin
Post date July 18, 2026

Band-Pass Filters - Do You Actually Need One?

Band-pass filters are common in serious contest stations and multi-operator setups, but what do they actually do… and do you really need one?

In this video I explain the difference between a notch filter and a band-pass filter, how modern transceivers already include front-end band-pass filtering, and why adding an external band-pass filter can further reduce unwanted signals and harmonics.

Using my own station as an example, I show why I use an external band-pass filter when running multiple stations at the same time, and discuss whether there are any benefits for a single-operator station.

We’ll also cover:

What a band-pass filter actually does
How it differs from a notch filter
Why flagship radios have sophisticated front-end filtering
Multi-station interference and harmonic suppression
Whether an external band-pass filter is worth the investment

I’d be interested to hear your thoughts. If you use an external band-pass filter, or you’ve found it made a noticeable difference in your station, let us know in the comments.

73,
